SPECIFICATION

Over Current Relay Testing System is a useful learning product for electrical laboratories. Over Current Relay monitors general balanced overloading and has current/time settings. These settings determine the protective schemes. The relay is IDMT type which has different tripping time characteristics with different current conditions. These are classified in accordance with their characteristic curves which indicate the speed of tripping operation. The typical settings for relay is 0.5-2 Amp in 1-10 seconds. 46617 has accurate voltage, current & time measurement. It includes built-in variable supply, digital voltmeter, ammeter, timer. The timer operation is automatic when current is applied to relay. This automatic operation ensures accurate tripping time measurement.
